An onlooker tells PEOPLE that the Dancing duo cast mates dined together at West Hollywood hot spot Delilah last night.

“They were giggly and seemed very comfortable together,” the onlooker adds.

Although Rose, 33, was eliminated from the reality dancing competition series on week 6, she seems to be finding happiness off the dance floor with her former pro partner Maksim Chmerkovskiy‘s younger brother!

Asked if any sparks were flaring between the two of them, Chmerkovskiy, 30, played coy and told Entertainment Tonight, “I can’t control what people think,” and added, “I live my life and I try to live it, you know, the way I want to live it.”
